The chloroplast, found only in algal and plant cells, is a cell organelle that produces energy through photosynthesis.The word chloroplast comes from the Greek words khloros, meaning “green”, and plastes, meaning “formed”.It has a high concentration of chlorophyll, the molecule that captures light energy, and this gives many plants and algae a green … Marine natural pigments: Chemistry, distribution and analysis. these complexes, CP I, had a high apparent molecular

The two most common types of chlorophyll are chlorophyll a, which is a blue-black ester with the chemical formula C 55 H 72 MgN 4 O 5, and chlorophyll b, which is a dark green ester with the formula C 55 H 70 MgN 4 O 6.Other forms of chlorophyll include chlorophyll … porphyrin. in assembly of light-harvesting complexes.

The chlorophyll molecule consists of a central magnesium atom surrounded by a nitrogen-containing structure called a porphyrin ring; attached to the ring is a long carbon–hydrogen side chain, known as a phytol chain.

Structurally, chlorophyll c is different from other chlorophylls in that it has a porphyrin ring structure without an isoprenoid tail or a reduced ring D. They have a trans acrylic acid at C-17 (ring D), instead of the propionic acid side chain of chlorophyll a and b, which in all polar chlorophyll c pigments is not esterified to phytol or other aliphatic long-chain alcohol.

Chemical Structure Chlorophyll is a chlorin pigment, which is structurally similar to and produced through the same metabolic pathway as other porphyrin pigments such as heme. This is very similar in structure to the heme group found in hemoglobin, except that in heme the central atom is iron, whereas in chlorophyll it is magnesium.
